STEAM-TRAP.

Specification of Letters Patent.

Patented June 2, 1908.

Application filed. July 15, 1907. Serial No. 383,724.

To all whom it may concern:

Be it known that 1, ROBERT WARG, a citizen of the United States, andresident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements in Steam-Traps; and I do hereby declare that the following is a full, clear, andexact description thereof.

The object of my invention is to provide a simple, durable and eflicientsteam-trap for radiators, steam-coils, heating-systems or the like, saidinvention consisting in certain peculiarities of construction andcombination of parts as hereinafter fully set forth with reference tothe accompanying drawing and subsequently claimed.

The accompanying drawing shows a longitudinal section view of asteam-trap embodying the features of my invention, with parts brokenaway and in section to more clearly illustrate the details.

Referring by letter to the drawing, A indicates a cylindrical casing andB a detachable head therefor, the casing being provided with asteam-inlet opening 0 and an outlet D, which outlet communicates with ahollow foot portion E of said casing.

The bottom wall of the casing is provided with a tappet-opening a, whichcommunicates with the foot E, said opening being adaptedto receive thethreaded end of a nipple F, into which nipple is tightly fitted a sleeveG as shown. This sleeve is preferably composed of hard copper, the upperedge of which forms a valve-seat, while the lower edge thereof abuts ashoulder 12 of the nipple. Seated upon the sleeve and forming a closuretherefor is a solid tobin bronze plunger H, which plunger together withthe hard copper sleeve comprises the trap discharge-valve. The plungeris provided with suitable guides c, 0, formed in a hood I, the loweropen-end of the hood being threaded for the reception of a correspondingthreaded shank of the nipple F, by which said hood is supported.

Condensation from the trap-casing is discharged through a series of 0enings d in the hood I, the said hood being a so formed with an ear e towhich is pivoted a slotted lever J, that is connected to the upper endof the plunger by means of a pin f, as shown. To one end of this leveris secured a stem 9 of a copper globe-float K, which is arranged to'open the valve when the condensation has -to permit clearance of thefloat, said well also serving as a cavity to receive any accumulation ofmud or sediment.

The upper wall of the casing is provided with a dome M to permit rise ofthe float when acted upon by the condensation, said dome being tappedfor a vent-cock N, while v the well L has a capped opening N therein forblow-off purposes, and a de ending support it as shown. The float isimited in its upward movement by a bridge-piece i of the lever, whichbridge-piece is adapted to engage the ear e of the hood.

In order to positively open the valve, the casing-head carries athreaded stem 0, which projects in the path of the bridge-piece "i, andmay be run in to engage the latter and thus lift the plunger from theseat, there being a hand-wheel j at the outer end of the stem foractuating the same.

From the foregoing description it will readily be understood that whenthe Waterline in the casing has risen to a suflicient height, the floatwill cause the valve to open, and thereby permit the condensation toflow freely through the hood and-thence to the outlet, until such timeas the float has dropped to its normal or closed position, causedthrough the discharge of said condensation.

The particular advantage of the construction of discharge-valvedescribed, is that the constant hammer of the hard metal plug upon thesoft-metal valve-seat tends to smooth off said seat and in a measureretain a perfect fit between the arts so as to prevent leak of thevalve. hould the seating of the arts however become imperfect throughlbng wear or other causes, the same may readily be repaired, accessbeing had to the valve by removing the head. This repair is accomplishedby removing the hood and facingoff the sleeve with a file or otherabrasive. The yoke and plunger may then be disconnected and said plungeralso refaced, after which a dressing of emery and oil may be applied toits face. The hood can now be readjusted to the nipple and the plungerdropped into place therein, and by revolving the same upon the sleeve orseat with a slight pressure the grinding motion will cause thecontacting faces to become perfectly seated with relation to each other.Thereafter the emery-paste is removed and the yoke being connected tothe hood the mechanism is again intact. The above operation can beresorted to from time to time as required without incurring thenecessary delay and expense in replacing the parts,

which heretofore has been the practice where valves of ordinaryconstruction are used. As the valve-seat is gradually worn down throughregrinding, it will cause a corresponding gradual sag of the float,which owing to the well formed in the ring, will not contact with thebottom thereof, the bridge piece 71 forming a stop as the float rises toprevent the same from striking the wall of the closure, as said valve iso ened.

The sleeve G is preferab y cut from a metallic tube section of standardconsistency and molded or otherwise secured into the nipple, thisconstruction being desirable for the reason that it is practicallyimpossible to cast the same in one iece with the nipple and retain auniform ensity of metal in all ni ples.

claim: 1. A float-valve comprising a nipple, a

sleeve fitted therein, an a' ertured hood in threaded connection with te nipple, guides in the hood, a reciprocative plunger fitted in theguides and adapted to seat upon the sleeve, an ear projecting from saidhood,a slotted lever ivoted to the ear, means connecting the p unger andlever, and a bridgepiece carried by the lever arranged to abut said ear.

2. A steam-trap comprising a closed casing having inlet and outletopenings, a ni ple secured to the outlet opening having a va veseattherein, a hood in connection with the nipple, a plunger valve-closurecarried by the hood, an ear projecting from the hood, a float-leverpivoted to the car, a bridge-piece extending from the lever arranged toabut said car, an adjustable spindle in threaded engagement with thecasing alined with the bridge-piece, float-lever and plunger valve.

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee in and means connecting the 30 the county of Milwaukee andState of Wisconsin in the presence of two witnesses.
